ACPI, APEI, Resolve false conflict between ACPI NVS and APEI Some firmware will access memory in ACPI NVS region via APEI. That is, instructions in APEI ERST/EINJ table will read/write ACPI NVS region. The original resource conflict checking in APEI code will check memory/ioport accessed by APEI via general resource management mech. But ACPI NVS region is marked as busy already, so that the false resource conflict will prevent APEI ERST/EINJ to work. To fix this, this patch excludes ACPI NVS regions when APEI components request resources. So that they will not conflict with ACPI NVS regions.
